But that would in fact introduce a Java 8 dependency on hibernate-core if
we did this directly. We could maybe use some form of "unwrap" notion
where hibernate-java8 could auto-register some delegate for "additional
param setting". We could use the same concept in relation to
hibernate-spatial as well for setting geolatte specific parameters.

As far as the Java 8 date/time stuff... see the hibernate-java8 module...
that is its whole goal... Optional support has a little more to it, some
of which is alluded to in this discussion

Um, why would we need extra*s*? We need one... for Optional.
